It attenuates higher than US-05 and flocculates better, leaving a cleaner, drier beer with hop character in front and nothing competing behind it.\u003c\/p\u003e \u003cp\u003e\u003cb\u003eBest Suited To\u003c\/b\u003e\u003c\/p\u003e \u003cul\u003e \u003cli\u003eWest Coast IPA, American IPA, Double IPA\u003c\/li\u003e \u003cli\u003eAmerican Pale Ale, American Amber Ale\u003c\/li\u003e \u003cli\u003eAny American ale where a dry, neutral fermentation profile is the goal\u003c\/li\u003e \u003c\/ul\u003e \u003cp\u003e\u003cb\u003eSpecs\u003c\/b\u003e\u003c\/p\u003e \u003cul\u003e \u003cli\u003e \u003cstrong\u003eFermentation temp:\u003c\/strong\u003e 18–23°C (optimal 19–21°C)\u003c\/li\u003e \u003cli\u003e \u003cstrong\u003eAttenuation:\u003c\/strong\u003e 75–80%\u003c\/li\u003e \u003cli\u003e \u003cstrong\u003eFlocculation:\u003c\/strong\u003e Medium-High\u003c\/li\u003e \u003cli\u003e \u003cstrong\u003eAlcohol tolerance:\u003c\/strong\u003e Up to 12% ABV\u003c\/li\u003e \u003cli\u003e \u003cstrong\u003ePitching rate:\u003c\/strong\u003e 1 sachet per 23L at standard gravity\u003c\/li\u003e \u003c\/ul\u003e \u003cp\u003e\u003cb\u003eWhen to Choose M44\u003c\/b\u003e\u003c\/p\u003e \u003cp\u003eChoose M44 over US-05 when dryness and clarity matter. M44 attenuates more aggressively and flocculates better — useful when the malt bill is heavier or when you want hop bitterness to dominate without residual sweetness softening it. US-05 is more forgiving and faster to start.\u003c\/p\u003e \u003cp\u003eChoose M44 over M66 when you are brewing West Coast, not hazy. M66 produces tropical fruit esters and permanent haze — right for NEIPA, wrong for a clear, bitter West Coast profile. M44 stays out of the way and lets the hops do the work.\u003c\/p\u003e \u003cp\u003e\u003cb\u003ePractical Notes\u003c\/b\u003e\u003c\/p\u003e \u003cp\u003eM44 has a longer lag phase than most dry yeasts. Twenty-four to 48 hours before visible fermentation is normal for this strain. Do not repitch — give it time.\u003c\/p\u003e \u003cp\u003ePitch directly onto wort at fermentation temperature, or rehydrate in 10x its weight in 27°C water for 15 minutes. Rehydrate and add yeast nutrient for beers above 1.065.\u003c\/p\u003e \u003cp\u003eFerment at 18–21°C for the cleanest result. Above 22°C ester character increases and works against the West Coast profile.\u003c\/p\u003e \u003cp\u003eKeep refrigerated. Once opened, reseal and use within 7 days.\u003c\/p\u003e \u003cp\u003e\u003cem\u003eReviewed by the AHB Brewing Team — June 2026.\u003c\/em\u003e\u003c\/p\u003e","brand":"Mangrove Jack's","offers":[{"title":"Default Title","offer_id":41994562928717,"sku":"25011","price":9.5,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0635\/8306\/0045\/files\/25011.jpg?v=1754053217","url":"https:\/\/www.australianhomebrewing.com.au\/products\/mangrove-jacks-beer-yeast-us-west-coast-ale-m44","provider":"Australian Home Brewing","version":"1.0","type":"link"}
